Applications: Contact microphone, Dynamic strain gages, Speakers, Switches

　　Description: The “F” in FDT Series stands for ‘Flexible Leads’. These are rectangle elements of piezo film with silver ink screen printed electrodes. Rather than making the lead attachment near the sensor, the piezo polymer tail extends from the active sensor area as flex circuit material with offset traces. This gives a very flat, flexible lead, with a connector at the end. The FDT elements are available in a variety of different sizes and thicknesses. They are available without a laminate (FDT), with a laminated (0.005” mylar) on one side (FLDT) or with tape release layer adhesive (FDT with adh) in the sensor area. The connector pins on the FDT sensors can be directly soldered to a PCB with a reasonable level of care. This component cannot withstand high temperatures (> 80°C), and therefore coldering of the pins to a PCB must be done quickly. A heatsink clamped to the interface area between the film and the crimps will take the heat away from the film. Pre-tin the pins and then quickly solder them to the board. Do not allow the soldering iron to touch the film, and do not use a dwell time of over 5 seconds on the pins. Low temperature solder can also be used.

　　产品描述:

　　"F"在FDT系列里代表“柔性引线”。FDT系列是带银墨丝印电极的矩形压电薄膜元件。与其他接出引线的压电薄膜元件不同，带电极的压电薄膜从动态传感区域延伸出来作为柔性电路板，末端带有连接头，从而使得传感器的引出非常扁平，而且柔软。FDT系列有许多不同的尺寸和厚度可供选择。客户可以选择没有聚酯基片的FDT，一面有聚酯基片（0.005”）的FLDT，或传感区域附有双面胶的FDT。FDT传感器末端的插针可直接焊接到PCB。元件不能承受高温（> 80°C），因此焊接需要迅速完成。夹在压电薄膜和连接头连接处的散热器能迅速把热量带走。提前给插针上锡，然后迅速焊接到电路板上。不要用烙铁接触压电薄膜，焊接时间也不能超过5秒钟。可用低温焊接。
